4-Methylenecyclohexane-1-carboxylic acid CAS 934-69-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Methylenecyclohexane-1-carboxylic acid (CAS 934-69-0), molecular formula C8H12O2 and molecular weight 140.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methylenecyclohexane-1-carboxylic acid (C8H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 140.18 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
